portions of filter plates for the purpose of securing filtering sheets thereto. The machine shown herein 1S particularly well adapted to apply clamping rings to the peripheral portions of filter plates of the type shown in my copending application No. 698,866 filed March 18, 1924-. I

It is the general purpose and object of the invention to provide a machine of this character which is simple in construction and economical of production, but which is capable of realizing the objects for which it is designed in a very eiiicient manner.

The foregoing objects will be accomplished in and through the construction shown in the accompanying drawings, where in Fig. 1 represents vertical sectional elevation of a machine embodying my invention, the receivingposition of its ring-1e.

ceiving and applying member being shown in dotted lines; Fig. 2 illustrates a plan view of a filter plate of the type with which the machine shown in Fig. 1 is particularly adapted to cooperate; Fig. 3 illustrates a transverse, central sectional view through the said plate; Fig. 4: is a sectional detail through the lower part of the ring-applying member; Fig 5 is a similar detail through the bottom of the ring-applying member and the top of the table or supporting member, showing the positions of the parts prior to applying a ring to the filter plate; and Fig. 6 is a similar view showing the posi tions of the parts at the time when the ring is applied to the plate.

The machine described herein consists generally of a table having a top constituting a base member A upon which the filter plate is supported, with a ring-applying member pivoted at one side of the top and having means for temporarily holding a ring, together with means for applying the ring to its peripheral sea-t upon the filter plate or other object,

As the machine is particularly intended to operate upon a filter plate of a type wherein the filtering sheets are drawn over the periphery of the plate and secured thereto by rings, a brief description of a plate of this character will now be given, the said plate being shown in detail in Figs. 2 and 3.

The plate" comprises a central hub 1 having a central bore 2 therethrough, with radial passages 3 extending outwardly from said bore, through saidhub, the said radial passages merging with througlrpassages a:

in the plate, and the ends of these passages in turn communicating with radial channel 5, which extend on each side of the plate to an annular marginal ledge 6. The pcriphery of the plate comprises a central radially extending circumferential rib 7, the upper and lower surfaces of the periphery forming two reversely extending cone frusta 8 and 8, each having its smaller base adjacent to the rib. The plate is preferably provided with circun'iferential triangular ribs on opposite sides thereof, between the ledges 6 and the hub 2, with an annular channel 10 on each side of the plate, between the ledges and hub, and an annular channel 11 on opposite sides thereof adjacent to the hub; also with long radial ribs 12 extending from each ledge inwardlyto the channel 11 and with short radial ribs 13 extending from each ledge to the channel 10.

A complete filtering element comprises a filter plate such as described with the opposite faces thereof covered with one or more sheets of filtering material extending from the bore 2 outwardly across the ledges 6, along the surfaces 8 and 8 and preferably along the upper and lower surfaces of the rib 7, together with the clamping rings which hold the peripheral portions of the filter sheets upon the seats formed by such surfaces. One of the clamping rings is shown at 14 in Figs. 1, 4, 5, and 6, and a sheet of filtering material for one of the surfaces of the plate is shown at 15 in the same views, the ring and the peripheral part of the sheet 15 being sllOwn in 'LTI (i in the positions which they occupy upon the assembled filtering element.

For the purpose of applying the rings to their peripherzi sets, the machine shown in Figs. 1, at, 5 and 6 is used. ihis machine comprises the member A having a table top 16 provided with a central circular depression 17 therein and with a short depending skirt 18 having; sockets 19 for the legs 20, the top beingshown as strengthened by the radial ribs 21 extending between the shirt and the depression 17. The central depiession 1'? is provided 'with a central aperture 22 in the bottom thereof, with an zinnulr-n' shoulder 23 surroundi the upper end of the aperture and projettg sieve the bottom of the depre, sien.- This shoulder ttoi s it seat for a hollow stud having an upper boo portioi 2% provided with an annular shonlde'i- -25 at the bottom; tliereo'tresting on the shoulder 23, and with it reduced necl; or' stem 96 fitting within the'hore E o end e"-' tending therethrough and provided at its lower end'with ti nut 2'? by'meansnt which the stu'd is drawn to its sent on the shoulder Q3. with a. bore hzivingnninternal thread 28, and the upperend of the studis preferably beveled or frustro-conical, shown it to tt'zeilitate the application of tie hub of a filter plate thereto.
